IMPROVEMENT IN nAunoAof-CAR sToves.

Specification forming part of Letters Patent No. 147,729, dated February 17, 1874; application tiled May 27, 1873.

To all whom Iit may concern:

Be it known that I, J Amts WILSON, of Doylestown, Bucks county, State of Pennsylvania, have invented an Improved Railroad- Car Stove, of which the following is a specification:

The. main object of my invention is to prevent railroad-cars from being set on iire by the heating-stoves in case of collision or other accidents, further obj eets being to produce amore uniform and agreeable heat, and to arrange the stove more conveniently than usual. I 'attain these objects in the manner Shown in the sectional view, Figure l, and plan view, Fig. 2, of the accompanying drawing, by suspending the heating-stove 'D beneath a register, A, in the oor of the railroad-car, and Surrounding it by a casing, B, y open at the bottom, through which and around the stove the air to be heated passes before .reaching the register, the air being mingled with vapor from a water-chamber, a., before entering` the ear, and the stove being convenient of access, but entirely closed when in operation, and so strongly constructed as to be capable of resisting the most violent Shocks without breaking and permitting` the escape of ignited coa-ls.

My invention will be fully understood from the following` detailed description.

rEhe register A rests upon an annular frame, A', let into and secured to the floor of the ear, the said register having on its under side a bolt or cross-bar, i, adapted to slots i in the frame, from which, by a slight turning movement, it can readily be withdrawn when it is necessary to lift the register from its place for 'the purpose of obtaining access to the stove beneath. rlhe latter is a self-contained strueture of great strength, consisting of a body, j, and of a cap-plate, b, secured to the top, and an annular frame, l, to the bottoni of the same Vby connecting-bolts m, as shown in the eXterior view, Fig. 3. A detachable ash-pan, k, is

suspended from the bottom of the stove beneath the grate b', which is capable of being rocked by a bar, lv', and there is a central opening, e, in the cap-plate, closed by a plug or stopper, f, having lugs g gat opposite sides, adapted to corresponding recesses and projections on the edges of the opening, within which it is thus Securely retained, but capable of bcing readily removed when it becomes necessary to replenish the stove with fuel. At one side of the cap-plate b there is a hollow projection, h, through which the products of combustion are conducted to the exit-pipe h', and between the said cap-plate and the top of the body of the stove is formed an annular airehamber, d, communicating with the external air through openings w', and with the interior of the stove through openings w, just above the mass of ignitedfuel, and serving the purpose of a gas-ring. The upper and lower portions of the stove are firmly secured together by bolts m, Figs. 2 and 3, as before remarked, and the whole structure is of such strength as to be capable of resisting the mostviolent shocks without breaking up and permitting the escape of ignited coals. It is formed with an annular shoulder, n, just beneath the airchamber, which rests upon, without being secured to, a ledge, p, of a frame, F, suspended from the loor of the car, this frame having openings q for the passage of air, and being constructed with an annular water-chamber, a, in its upper part, above the stove and within the outer casing B, the water in which, as it becomes vaporized, escaping through small apertures or a narrow annular passage, x, into the space beneath the register, and mingling with the heated air before it enters the car. The casing B is entirely open at the bottom, so that air can freely enter the same, and pass upward around the stove, becoming hi ghlv heated before entering the carp After removing the rcgister,the stove can be lifted bodily from its supportingframe F,

and removed from the car, this being preferably done inthe summer season when the easing B and register will form an eflicient ventilater.

rlhe hollow projection It at one side of the stove, besides serving as a smoke pipe, is adapted to a recess, s, in the frame F, through which it must be passed in lowering the stove into and raising it from its place, it therefore serving also as a guide to determine the proper position of the said stove. I claim as my invention- 1. The stoveD having afianoc or shoulder a e c 7 A'rnN'r (murena cess in the supporting-frame F, and serving the twofold purpose of a smoke-pipe and of a guide for determining the proper position of its stove upon the said supporting-frame.

In testimony whereof I have signed my name to this specifica-tion in the presence of two subscribing witnesses.

.JAMES wrLsoN.
